The diagram shows a circuit with four voltmeter readings V, V₁, V₂ and V₃. [Figure 35.1] Which equation relating the voltmeter readings must be true?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

AV = V₁ + V₂ + V₃

BV + V₁ = V₂ + V₃

CV₃ = 2(V₂)

DV - V₁ = V₃

✓ Correct answer

D: V - V₁ = V₃
